Setting fullscreen using other ways besides getting screen size in Java

Question

I was wondering if there was a way that is better than using the Toolkit.getDefaultToolkit().getScreenSize().getHeight()/getWidth(); and then using that as the dimensions for the JFrame and then setting the JFrame to undecorated? Would there be some sort of pre-built function in Java that takes control of the graphics card for a true fullscreen?

Answer 1

You're after what's called "full-screen exclusive mode"

Have a look at Full-Screen Exclusive Mode for more details.

Understand though, it doesn't play well with Swing.

Under Mac OS X 10.7, you can access the full screen support it provides for applications using com.apple.eawt.Application.requestToggleFullScreen(Window).
